Dynamite is highly explosive. This is because it's a chemical reaction waiting to happen. Chemical reactions happen all the time - even inside us! Reactants change to make new products. Explore physical and chemical properties of the substances that surround us in this explosive physical science e-book. From decomposition to acid-base reactions, fifth grade readers will learn about six types of chemical reactions; activation energy and hopping electrons; reactivity, catalysts, and inhibitors; physical changes of mixtures; and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on "Think Like a Scientist" lab activity and a "Your Turn" page at the end of the e-book support STEM Education and provide young scientists with an opportunity to apply what they've learned in the text. Helpful diagrams and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
